摘要:
As the ceramic powder fated to form dielectric ceramic layers in a multilayer ceramic electronic component resulting from alternately stacking the dielectric ceramic layers and internal electrode layers, a ceramic powder that possesses a perovskite-type crystal structure and satisfies an expression X≧3, wherein X denotes the weight ratio Wt/Wc of the tetragonal phase content Wt and the cubic phase content Wc, is used. The weight ratio Wt/Wc of the tetragonal phase and the cubic phase is determined by the polyphasic analysis in accordance with the Rietveld method. The ceramic powder is a barium titanate powder, for example. The specific surface area of the ceramic powder is in the range of 4 to 10 m2/g.

As the ceramic powder for addition to the electroconductive paste fated to form internal electrode layers in a multilayer ceramic electronic component resulting from alternately stacking the dielectric ceramic layers and internal electrode layers, a ceramic powder that possesses a perovskite-type crystal structure and satisfying the condition that the weight ratio Wt/Wc of the tetragonal phase content Wt and the cubic phase content Wc be not less than 2 is used. The weight ratio Wt/Wc of the tetragonal phase and the cubic phase is determined by the polyphasic analysis in accordance with the Rietveld method. The ceramic powder is a barium titanate powder, for example.
